CAR-COUPLING.

Specification of Letters Patent.

Patented Jan. 29, 1907.

Application filed July 9,1906. Serial No. 325,334:-

To wZZ whom it may concern:

Be it known that I, DAVID PATTERSON, a citizen ofthe United States, residing at Denver, in the county of Denver and State of Colorado, have invented new and useful Improvements in Oar-Couplers, of which the following is a specification.

My invention pertains to car-couplers and it contemplates the provision of a coupler constructed witha view of being used to advantagein handling mixed trains of broadgage cars and narrow-gage cars, the term cars as herein employed being intended to comprehend locomotives as well as other cars.

The invention also contemplates the provision of improved means for utilizing fluidpressure in raising the draw-bar of the coupler, especially when the coupler is employed on a locomotive-tender.

Other advantageous characteristics peculiar to my invention will be fully understood from the following description and claims when the same are read in connection with the accompanying drawings, forming part of this specification, in which Figure 1 is afac'e view of a coupler constructed in accordance with my invention and equipped with a hand-lever for raising the draw-bar. Fig. 1 is a perspective view of the draw-bar carrier removed. Fig. l is a detail horizontal section-taken through the plate or frame of the couplerin the plane indicated by line 1' 1 -of Fig. 1. Fig. 1 is a detail sectional erspe'ctive view of said plate or frame, sowing oneof the vertical lips c merging into a horizontal lip c. Fig. 2 is a side elevation ofthe coupler with the closure-bar at one end of the horizontal guideway in the bed-plate removed and illustrating the coupler as provided with fluid-pressure means in addition to the hand-lever for raising the draw-bar.

Similar letters designate corresponding parts in all of the views of the drawings, re-

A is a beam, which may be the pilot-beam or the back tender-sill of a locomotive or the end sill of a car, and B istheplate or frame of the coupler constituting the present and preferred embodiment of my invention. The said plate or frame is bolted to or otherwise fixed on the beam A and is provided with a horizontal guideway a and an upright guideway I), the latter communicating with and extending upward from the middle of the former, as best shownin Fig. 1. These guideways a and I) have lips or flanges c, and'it will be noted that the upper lips or flanges of the horizontal guideway merge into the lips or flanges of the upright guideway. It will also be. noted that the ends of the horizontal guideway a are closed by bars d, bolted or otherwise fixedlyconnected to the bed-plate B.

In the portions of the bed-plate B at opposite sides of the lower art of the upright guideway b are formed alined horizontal apertures e, which receive a removable horizontal pin O, designed to serve a purpose presently pointed out..

D is a cap-plate connected to the upper edge of bedplate B and arranged to close the upper end of the upright guideway'b. E is a block movable vertically in the upright guideway b and behind the lips 0 thereof, and F F are headed pins connected to the block'E and extending through the caplate D and designed to suspend the block when the latter is in its lowermost position. The block E has a lip c, which when theblock moves downward assumes a position between the upper lips c of the horizontal guideway a, and from this it follows that the block makes continuous the lower guideway a as well as the upper lip thereof. Said block E also has a groove f in its upper portion, which is designed when the block is in its lower position to seat the pin C, Fig. 2 whereby itwill be seen that said pin is enabled to hold the block against casual upward movement.

G is a draw-bar which is movable vertically and horizontally in the guideways of bedplate B and is provided with a transverse aperture g, designed when the draw-bar is raised to receive the pin O, and H is the drawbar carrier to which the draw-bar is connected, preferably through the medium of a pivotpin I. (Shown by dotted lines in Fig. 2.) The said carrier H is movable in the guideways a and I) back of the lips 0 thereof and is preferably provided with forward extensions h, disposed above and below the draw-bar G, as best shown in Fig. 2.

As shown by dotted lines in Fig. 1 and by full lines in Fig. 1 the carrier H is square in front elevation and is of a size to snugly fit and slide in the horizontal guideway a and upright b of the plate or frame A.

J is a hand-lever fulcrumed at k on bedio5 I plate B and having a hook l at its inner end designed to be engaged with an eye m on draw-bar G. This lever J is designed more particularly for use in raisin the draw-bar G and the carrier H when the raft attachment is applied to a car.

K, Fig. 2, is a lever designed more particularly for use in lifting the draw-bar G and carrier H when the draft attachment is applied to a locomotive or the tender thereof. The said lever K is provided on one arm with a rod L, which extends up through an a erture in the bed-plate B and is disposed be ow the lower extension h of carrier H. The other arm of lever K is connected to a piston M, arran ed in a cylinder N, designed to be connected with a source of fluid-pressure supply, and hence it will be apparent that when fluid-pressure is let into the cylinder N above the piston M the draw-bar G and its carrier H will be raised, while when fluidpressure is exhausted from the upper portion of cylinder N the draw-bar G and its carrier H will gravitate to their lowermost position.

In practice when the draw-bar G and its carrier H are raised to the upper portion of the upright guideway 12 in bed-plate B and are locked by the pin C the said draw-bar G is in position to handle broad-gage cars and equi ment. When, however, it is desired to han le narrow-gage cars and equipment, the draw-bar and its carrier are dropped to the bottom of the horizontal guideway a, where they may be freely moved toward the right or toward the left as may be necessary because of the narrow-gage or third rail being on the right or left side of the broad-gage track. It will also be understood that when in the lower position the draw-bar and its carrier will move automatically from right to left or left to right when the narrow-gage or third rail passes from one side to the other of the broad-gage track.

It will be gathered from the foregoing that the block E follows the draw-bar G and carrier H on the down movement thereof and is raised by said draw-bar and carrier when the same are moved upward.

hen my novel draft attachment as a whole is inverted and applied in such position to a narrow-gage locomotive or car, it is adapted for coupling same to a broad-gage car or locomotive, the horizontal guideway beingin this case used for broad-gage cars and the upright guideway for narrow-gage cars.

I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the said embodiment. I do not desire, however, to be understood as confining myself to the said specific construction and relative arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my invention as claimed.
